Donald Trump, whom more than a dozen women have accused of sexual misconduct, has made no secret of his distaste for the #MeToo movement, defending both longtime pal Roger Ailes and ex-Fox mega-host Bill O’Reilly against charges of sexual misconduct (Ailes he called a “very, very good person,” while of O’Reilly he said, “I don’t think Bill did anything wrong.”). But in February, the president made his position on #MeToo even more explicit: the day after defending former staff secretary Rob Porter, who resigned amid allegations of domestic abuse from two of his ex-wives, Trump tweeted that “lives are being shattered and destroyed” by “mere” allegations. “He says he’s innocent, and I think you have to remember that,” Trump said the day prior. “He said very strongly . . . that he’s innocent.” The comments inspired a wave of disquiet among those inclined to support women in speaking out about harassment and abuse. And on Thursday, the president revived his rhetoric during a bizarre rally in Montana ostensibly intended to stoke support for the state’s Republican Senate candidate.

Riffing on his nickname for Senator Elizabeth Warren, whose Native American heritage he has repeatedly questioned, Trump—who made no mention of the hasty same-day resignation of E.P.A. chief Scott Pruitt—told the crowd, “I want to apologize. Pocahontas, I apologize to you . . . to you I apologize. To the fake Pocahontas, I won’t apologize.”

He went on to suggest that if Warren won the 2020 Democratic primary, he would dare her to take an ancestry test during a televised debate. “We’ll take that little kit and say, we have to do it gently because we are in the #MeToo generation, so we have to be very gentle. And we will very gently take that kit, and we will slowly toss it” to Warren, “hoping it doesn’t hit her and injure her arm.” Trump added that he’d give $1 million to charity if the test “shows [Warren is] an Indian . . . I have a feeling,” he said, “she will say no.”

Nor did Trump confine himself to insulting a potential Democratic opponent—during the same speech, he also claimed that Democratic Rep. Maxine Waters had an I.Q. in the “mid-60s,” lobbed derogatory criticisms at journalists, and vouched for Russian President Vladimir Putin. After the rally, Warren fired back with a tweet, writing, “Hey, @realDonaldTrump: While you obsess over my genes, your Admin is conducting DNA tests on little kids because you ripped them from their mamas & you are too incompetent to reunite them in time to meet a court order. Maybe you should focus on fixing the lives you’re destroying.”

The president’s particular strain of misogyny has been on display for much of this week—earlier on Thursday, Trump told reporters that he doesn’t believe allegations that G.O.P. Rep. Jim Jordan knew about the sexual abuse of student athletes while he was a coach at Ohio State University. (Jordan himself has denied them.) “I don’t believe them at all,” Trump said of Jordan’s accusers, adding that he believes in Jordan’s innocence “100 percent”. Thursday also happened to be the day the White House officially hired Bill Shine, the former Fox News co-president who allegedly covered for Ailes for years. In making such statements, Trump seems to be indicating that no line of attack is off-limits—a tactic that successfully set him apart from a crowded Republican field in 2016.

He’s also setting a deeply toxic precedent for the 2020 presidential race—particularly if he faces off against another woman. And though this strategy is likely to appeal to his base, potentially deepening the gulf between people who believe women when they say they’ve been forced to endure sexual harassment and people who don’t, it is not without risk for Republicans. Not only could it further galvanize Democrats, but it could also alienate women voters who, according to a poll published on Friday, have a disproportionately negative view of the president: just 32 percent of women approve of his job performance, compared to 51 percent of men.
